the aim of this paper is to calculate the binary and triplet distribution functions for dilute relativistic plasma in terms of the thermal parameter μ where , is the mass of charge;c is the speed of light;k is the Boltzmann’s constant;and t is the absolute temperature. Our calculations are based on the relativistic Bogoliubov-Born-green-Kirkwood-Yvon (BBgKY) hierarchy. We obtain classical binary and triplet distribution functions for one- and two-component plasmas. the excess free energy and pressure are represented in the forms of a convergent series expansions in terms of the thermal parameter μ.

这篇报告叙述了X波段低噪声行波管的结构和工作特性。关于行波管的低噪声性能设计在本刊1963年第五期的译文中已经讨论过。这里只介绍一些实际的问题。研制中做成了五只管子,在8到11.6千兆赫频段中最终设计的噪声系数在10.5分贝以下。在同样的频段内,增益大于30分贝。在8.3千兆赫测得的最低噪声系数为8分贝。

Objective: this paper aims to study the sociodemographic and clinical aspects of menopausal climacteric syndrome in the city of Kati in Mali. Patients and Methods: this was a quantitative descriptive and cross-sectional study, conducted in the city of Kati from February 1 to July 31, 2021. We included 112 menopausal women. Women were selected from a household survey using the sampling step. We were interested in conjugal, family and professional life, self-esteem and the state of health of women in general. Results: More than half of the women in our study were already postmenopausal (52.2%);the mean age was 50.5 years with the extremes ranging from 41 to 62 years. the majority of them were married (69.9%), housewives (43.4%) and Bambara (53.1%). the most common climacteric syndromes were: joint pain (65.5%), hot flashes (62.8%) and night sweats (56.6%). genital-urinary syndromes (42.5%) were dominated by decreased libido (41.7%), urinary disorder (23%) and vaginal dryness (14.6%). genitalia-urinary syndromes increased the frequency of disagreements;Pearson’s Chi-square = 33.63;ddl = 1;P = 0.001. there was a statistically significant relationship between night sweat, genital-urinary syndromes, joint pain, and increased disease frequency with, respectively: Pearson’s chi-square = 4.660;ddl = 1;P = 0.031;Fisher’s exact test, P = 0.001, Pearson’s Chi-square = 8.434;ddl = 1;P = 0.004. there was no statistically significant relationship between climacteric syndrome and family life, work life and self-esteem. Changes in the professional relationship between women and their co-workers included, respectively: arguments (50%);disagreements (25%) and disobedience (25%). Conclusion: Menopause deteriorates the quality of life of women who suffer in silence, hence the need to pay special attention to them.

介于1到8个太阳质量之间的恒星在演化后期的渐近巨星分支(AgB)阶段,会以气体和尘埃的形式损失大量物质.AgB星提供了星际介质中高达35%的尘埃,其中包含形成太阳系所需要的物质.此外,AgB星周包层是复杂有机化学所发生的重要场所之一,在其中已探测到的有机分子已超过80多个.这里展示了AgB星自身或者其近距离的伴星所辐射的紫外光子会显著地改变星周包层的化学特性,尤其是具有团块结构的星周包层.研究发现,在恒星存在伴星(例如白矮星)的情况下,高通量的紫外光子会破坏富碳AgB星周包层内部的H2O分子,使其含量低于观测到的水平,并且在星周包层内部产生C^+等物质,这与以往的星周化学模型的研究结果是不同的.

转基因技术是近十几年发展起来的一种新型治疗手段进入90年代以来,阳离子聚合物以其低付作用,高效率得到国际学术界及工业界的广泛注意。本文报导了低分子量聚乙烯亚胺作用非病毒型载体用于基因转移方面的研究。通过激光光散射及核磁共振谱的研究发现低分子量聚乙烯亚胺具有较低的支化度及分散性,同时具有较高的旋转半径等性质,在细胞培养实验中发现,与目前众多研究小组常用的商业化高分子量聚乙烯亚胺进行比较,低分子量聚乙烯亚胺在一个相当宽的浓度范围内具有相当低的毒性,同时在转基因实验中发现,其转移效率较之高分子量聚乙烯亚胺而言,增加了100倍左右,显示其作为一种新型的载体在转基因技术中的优势。
